Adjustment of personal expense refund on credit card

Adjustment of personal expense refund on credit card

I have bought 5 items as personal expenses  on credit card , as single payment, shown as owner's drawings.
Few items i.e., 2 ,were returned, so the refund amount doesn't match the exact payment made. 
How can i adjust refund amount against the expenses.
There is no owner's contribution shown in credit card , is there any other ways ? Please help.
